SLIDING SCREEN vAND BLIND.

SPECIFICATION forming part of Letters Patent No. 531,828, dated January1, 1895.

Application filed September 8, 1894. Serial No. 522,415. (No model.)

To all whom it may concern.-

.Be it known that I, GEORGE E. BLAINE, a citizen of the United States,residing at Alliance, in the county of Stark and State of Ohio, haveinvented certain new and useful Improvements in Sliding Screens andBlinds; and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My invention relates to improvements in that class of sliding screensand blinds for windows, which comprise a frame having grooves in itsside bars, extensible strips having reduced portions adapted to enterthe grooves in the side bars of the frame, and springs interposedbetween the extensible strips and the side bars of the frame; and itconsists in the peculiar construction, novel combination and adaptationof parts hereinafter described and particularly pointed out in the claimappended.

In the accompanying drawings Figure l, is a face view of a window frameor casing, illustrating my improvements as applied to a screen andplaced therein. Fig. 2, is an enlarged, detail view partlyin seotion,andpartly broken away. Fig.' 3, is a detail, sectional view taken in theplane indicated by the dotted line vas, es, on Fig. 2. Fig. 4, is aperspective view of one of the guide plates removed, and Fig. 5, is aperspective, sectional view with parts broken away, of one of theextensible, side-strips or bars.

Referring by letter to said drawings:-A, indicates a window casing,which may be of anyordinary or approved construction. This casing isprovided on the inner sides of its stiles with vertically-disposedguide-strips o., and these strips when used in connection with thecharacter ot' groove which I have illustrated tin the side bars orstrips of the screen or blind frame, should be rounded or beveled,although it is obvious that they may be of an angular form or othersuitable shape to correspend with the shape of the grooves provided inthe side strips on thescreen or blind frame.

The frame B, which may be that of a tly screen or blind is of arectangular form in outline, and when used as a screen, should have awire netting b, covering the opening.

This frame comprises the upper and lower cross-bars c, and d, and thelateral, vertical bars e. The lateral bars are provided in their outerside throughout their length with a central, angular groove f.

C, indicates the extensible, lateral strips. These strips are providedon their outer sides or edges with longitudinal grooves g, correspondingto the configuration of the guide strips to be placed in the Stiles ofthe window casing, and are designed to receive the latter. The innersides of these strips C, are rabbeted as shown at h, and rl, so as toform a proportionately long tongue to enter the grooves or recesses f,of the lateral bars e, of the frame; springs such as D, and illustratedin dotted lines, being placed within the grooves f, and back of thetongues 7o, so as to keep the strips or bars C, normally extended.

E, indicates guide plates; there being four employed. These plates areof a peculiar construction and for the sake of cheapness in manufacture,are formed from sheet metal, and are provided with an elongated slot j,for the passage of a guide pin or screw Z, which takes into the top andbottom cross-bars of the frame B, as shown; the head of the piu or screwlying on the outer side ot' the plate so that said plate may slide trueand yet be prevented from casual displacement. The opposite or outerends of these plates are secured to the ends of the spring backed,extensible strips C, by nails, screws, or other suitable fasteningdevices. The plates in addition to serving as guides, serve the functionof strengthening the tongues 71:. To do this, the plates are cut or slittransversely as shown at m, and thence longitudinally of the plate asshown at n, leaving the parts p, intact, and there is one of theseslitted portions arranged opposite each other and out of thelongitudinal center of the plate. By thus slitting the plate, I providetwo tongues q, which I turn inwardly at au angle and snugly against theopposite side 0E the tongues 7o, of the extensible strips, as by thismeans I effectively strengthen the tongues and prevent them fromslitting or otherwise becoming inj ured. These strengthening tongues arepressed suficiently into the strips as not to interfere with the freemovement of said strips in the grooves f, of the lateral rails or bars.A frame as thus IOO constructed may be produced at a compaia tivelysmall expense. It is very effective for the purposes designed, and thereis nothing about it to get out of order. It will also be observed thatthe friction will be equal on both sides of the window, and that thereare no nails, screws, or like devices employed for holding the springs.

Having described my invention, what I claim is- The herein describeddevice consisting essentially of the rectangular frame B, having itslateral or vertical side bars e, provided in their outer sides withgrooves or recesses which extend throughout their length, the eX-tensible strips C, having longitudinal grooves in their outer sides andrabbeted on opposite sides to form the tongues or reduced portions k,adapted to enter the grooves or recesses in the side bars of the frameB, springs arranged in the grooves or recesses of the lateral bars e, ofthe frameB, and interposed between said lateral bars and the reducedportions le, of the extensible strips C, the guide plates E, arrangedabove and below the frame B, and having the elongated slots j, and theintegral tongues q, embracing the tongues or reduced portions la, of theextensible strips, pins or screws secured to the lateral bars ot'. theframe and passing through the slots j, of the plates E, and pins or thelike for securing the plates E, to the ends of the extensible strips,substantially as and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.

GEORGE E. BLAINE.
